Re: Heated side view mirrors Hmmm, that's a good point Mafix. Thanks You are correct, the door harness is different b/c it would have those heating wires in it. I'll remove what I can of the mirror wiring harness and go from there. Cold time of year to be messing with this stuff!
get a set of heated with the pigtails from a member or junkyard. then wire the stock mirror controls to your existing harness. the just run the 2 wires for the heater right on top of the stock harness. mabye even make a quick connect near the door harness connection in case you have to remove doors later. hell even polarity doesn't matter so wiring will be a breeze. i think the hatch heater wire even runs down the drivers side. so i'd just tap in there.
As the electrical wiring has a tendency to baffle me, I really appreciate the advice. I'll try what you suggested. Thanks Mafix :mrgreen: PS - If it's successful, I'll do a write-up.
Edit: 86 GTS mirrors are non-heated; 87 GTS, 88 GTS & 89 GTS' and All-Trac are heated. The 86 GTS is, however, pre-wired to accept the heated 5-pin mirrors. It's a straight bolt-in :mrgreen: ST and GT mirrors are non-heated from 86-89, in Canada.
